Examples

Every method and class is full documented, so here are several examples, i.e. just a one for each class.

ArrayHelper, indexing an array.

$array = [
    ['id' => '123', 'data' => 'abc'],
    ['id' => '345', 'data' => 'def'],
];
$result = ArrayHelper::index($array, 'id');
// The result is:
// [
//     '123' => ['id' => '123', 'data' => 'abc'],
//     '345' => ['id' => '345', 'data' => 'def'],
// ]

FormHelper, generating a source array for a select element.

$array = [
    ['123' => 'abc'],
    ['345' => 'def'],
];
$result = FormHelper::generateList($array);
// The result is:
// [
//     ['id' => '123', 'name' => 'abc'],
//     ['id' => '345', 'name' => 'def']
// ]

// The usage in a form definition:
array(
    'type'    => 'select',
    'label'   => 'Example',
    'name'    => 'example',
    'options' => array(
        'query' => $result,
        'id'    => 'id',
        'name'  => 'name',
    ),
)

LogHelper, logging an error in a module.

public function example() {
    $this->log('An error occupied.');
}
public function log($messages, $level = AbstractLogger::WARNING) {
    LogHelper::log($messages, $level, $this->name, $this->id);
}

DiagnosticHelper, checking if a method is overridden.

if (DiagnosticHelper::isMethodOverridden('AddressController', 'init')) {
    $this->_errors[] = $this->l('The AddressController::init() already overridden.');
}

AjaxModuleFrontController, creating a simple Ajax controller for a module.

class ExampleAjaxModuleFrontController extends AjaxModuleFrontController {
    protected function actionSave() {
        $this->ajaxResponse->result  = true;
        $this->ajaxResponse->message = 'Success!';
    }
}
// The output result is:
// {"result":true,"data":null,"html":"","message":"Success!","errors":[]}

ModuleHelper, getting an instance of a module by given directory path.

$path   = '/var/www/prestashop/modules/homecategoriez/classes'; 
$module = ModuleHelper::getInstanceByPath($path); /** @var HomeCategoriez $module The instance of the module: HomeCategoriez */

FileHelper, getting a real maximum file size that can be uploaded to a site.

$sizeInBytes = FileHelper::getFileSizeUploadLimit();

Cache component, caching a DB query result.

public function getAllCustomers() {
    $cacheKey = CacheProvider::getKeyName(__METHOD__);

    $data = CacheProvider::getInstance()->get($cacheKey);
    if (false === $data) {
        $data = Db::getInstance()->executeS('SELECT * FROM ps_customer', true, false);
        CacheProvider::getInstance()->set($cacheKey, $data, 60 * 60 * 24);
    }

    return $data;
}

Autoloader, using Composer's autoloader to automatically load PHP classes, for example, in a module by adding classmap to your composer.json file.

"autoload": {
  "classmap": [
    "classes/",
    "interfaces/"
  ]
}
